A coaxial cable includes an internal conductor, an insulator that is provided at an outer circumference of the internal conductor, a film that is provided at an outer circumference of the insulator, an external conductor that is provided at an outer circumference of the film, a sheath that is provided at an outer circumference of the external conductor, and an adhesive layer that is provided between the insulator and the film and that bonds the insulator and the film with each other.

A cable includes: at least two cores for transmitting signals, a first insulator and a second insulator each wrapping one of the cores, and a shielding sheet. The first insulator has a first surface, the second insulator has a second surface urging against the first surface, and at least parts of the first surface and the second surface are not overlapped. The shielding sheet has a wrapping portion, and a first end portion and a second end portion located on two sides of the wrapping portion. The wrapping portion longitudinally wraps around both the first insulator and the second insulator in the direction parallel to axes of the cores, such that a space is formed between the shielding sheet, the first surface, and the second surface. The first end portion and the second end portion bend and enter the space.

A cable is specified, specifically for a signal line, which extends in a longitudinal direction and which includes an inner conductor and also an outer conductor. Between the inner conductor and the outer conductor there is formed an insulating material which surrounds the inner conductor and which has a surface that has been at least partially carbonized. Furthermore, a production method for such a line is specified.

A method of manufacturing a coaxial cable includes: providing an intermediate construction for a coaxial cable comprising an inner conductor, a dielectric layer circumferentially surrounding the inner conductor, and a smooth outer conductor circumferentially surrounding and adhered to the dielectric layer; and impressing corrugations into the outer conductor and corresponding protrusions in the dielectric layer.

A cable, especially a data transfer cable, has at least one wire having an inner conductor and a wire sheath which has been applied directly thereto. The wire sheath has a dielectric layer composed of a foamed uncrosslinked thermoplastic polymer, preferably polyethylene or polypropylene, and the dielectric layer is encased by an outer skin layer composed of unfoamed, chemically crosslinked polyethylene. The specific wire sheath leads to a distinct improvement in soldering properties. Additionally specified are a corresponding wire and a production process therefor.

A method for applying a polymer film onto an electric conductor joint includes providing an electric conductor joint (2) oriented in a cable direction (A1), providing a roll (32) with a polymer film (31), and securing an end of the polymer film (31) to the electric conductor joint (2). The roll is moved about the electric conductor joint thereby releasing the polymer film from the roll and rotating the roll about an longitudinal center axis. The roll is oriented with the longitudinal center axis parallel with the cable direction during the movement of the roll about the electric conductor joint.
